Connecting to one of the FXS ports
Use this configuration to connect paging equipment that interfaces through a telephone
line. Typically, any OHP that connects to an FXS port has some intelligence to go off and
on hook or otherwise send a signal back to the pager. These are generally controllers or
telephone interfaces with controls and settings.
In this configuration, you can specify a paging delay on the WebUI to compensate for the
fixed delay introduced by the OHP system. This delay ensures that the paging tone is
played simultaneously on both Desksets and on the OHP system.

Multi-Zone Paging
Multi-zone paging broadcasts to speakers grouped into separate zones. Since the
multi-zone OHP systems require zone selection, they cannot be combined into one zone
together with Synapse Desksets. A multi-zone paging system must connect to one of the
ATA FXS ports.
When paging is configured as a multi-zone OHP, a dedicated Overhead Paging zone
automatically appears as the last entry in the Deskset paging menu.
Figure 7. Multiple-Zone Overhead Paging on FXS Port
Overhead paging cannot be added to Synapse-specific paging zones because
the multi-zone OHP cannot be paged together with Desksets.
